Thanks for adding .Png image for mono screen (24 bits 3 pixels in…) option in slicer.
I have 2 printers Nova3d Bene4 and Whale2 and wrote my own Java converter for them from grayscale PNG.
Your format suitable for Bene4 mono but not for Whale2 because Whale2 have reverse order of pixels.
As you can see difference in RGB order - in one case RGB in other BGR
Please add one more option where “.Png image for mono screen” have BGR order.
I killed a lot of time understanding why my printer prints with “bad resolution” when adopt my bene4 plugin to whale2.
You can check my info comparing edges of white areas in Nova3d NovaMaker slicer images. In one case edges blue at right (whale2) in other case blue at left (Bene4 mono)
I think you will appreciate my contribution to the development of your slicer
